El Paso's purple streetlights ongoing problem due to nationwide LED defects

If you drive around El Paso and the county in the evenings, you might have noticed purple streetlights. Last year, KFOX14 reported that these lights were defective and needed replacement. However, despite efforts, many of these purple-hued streetlights still remain in different parts of town, including Eastlake Boulevard, Alameda Avenue, Mesa Street, and Delta Drive.

Andres Rico, the City of El Paso Transportation Manager, explained that this issue is not unique to El Paso—it’s a nationwide problem. The cause of the color change in these traffic streetlights lies in a coating failure on the LED bulbs. The natural light emitted by the LED is a purple and blue hue, but the phosphorus covering applied to the light bulb eventually burns off, resulting in the distinctive blue hue we see.

The company that supplied these lights has been able to identify the states and cities where the defective batches were sold, allowing them to be proactive in addressing the outages. Our sister stations in Illinois, North Carolina, and Maine have also reported similar purple streetlights due to the same lighting defect.

Solvent sieve method sets new record for perovskite light-emitting diodes

Using a simple solvent sieve method, researchers from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) have taken the lead in developing highly efficient and stable perovskite light-emitting diodes (PeLEDs) with record performance.

Perovskites are one of the most promising optoelectronic materials due to their excellent optoelectronic performance and low preparation cost. Compared with traditional organic light-emitting diodes (OLEDs), PeLEDs have a narrower light-emitting spectrum and superior color purity, thus showing great application potential in display and lighting.

However, despite significant progress in efficiency, low operational stability has long limited the practical application of PeLEDs. In particular, a limited understanding of the cause of perovskite instability has greatly hindered the development and commercialization of PeLEDs.

Inspired by the process of separating sand of different sizes with a sieve, the researchers proposed a solvent sieve method to screen out these undesirable low n-phases.

According to the researchers, the solvent sieve is a combination of polar and nonpolar solvents. The polar solvent acts as a mesh that interacts with perovskites, while the nonpolar solvent acts as a framework that does not affect perovskites. The researchers adjusted the ratio of polar solvents to effectively remove the defective low n-phases.

Fluence and Innexo BV’s Research Partnership Explores Eliminating Vegetation Phase to Drive Potential Energy Savings for Growers

Fluence, a global provider of energy-efficient LED lighting solutions for commercial cannabis and food production, announced the continuation of its partnership with Dutch organization Innexo BV (Innexo), a specialty agricultural contract research organization that focuses on molecular farming and medicinal plants.

Fluence and Innexo’s research partnership is focused on assessing the viability of cultivating cannabis without a standard vegetative phase, a practice generally associated with lower energy use that passes savings directly to growers in Europe and around the globe. Preliminary data from Fluence and Innexo demonstrates the potential of the “no-veg” growing method to help growers save money while improving quality and consistency. The Fluence and Innexo teams intend to collaborate on a full-scale research project to validate these initial results.

Most commercial cannabis cultivators use a vegetative phase to ensure proper plant growth to support flower weight and to gain a full and dense canopy. This phase can last anywhere between seven days and four weeks, requiring a significant investment of time, electrical energy and resources. Initial findings from Fluence and Innexo demonstrate the potential of this method to maintain crop quality and yield while creating up to 55% savings on annual electrical costs directly associated with lighting.

When the plants would typically enter the vegetative phase, they were instead transplanted to the flowering room, where they immediately received their maximum light intensity. In this system, cannabis crops reach their final height—between 70 and 120 cm—around 28 days after transplant. Eliminating two weeks of vegetative phase represents up to 252 hours of direct electricity savings per light per crop cycle. Additional savings are realized through lower HVAC costs and generally more efficient cultivation cycles. Initial research indicates that “no-veg” growing is most effective with plant densities between eight and 10 plants per m2.

IlluminOss Receives 510K Clearance for a New Light Console for its Implants that Provide Strength for Fragile and Geriatric Bone

IlluminOss Medical announces it has received FDA 510(k) clearance for a new Light-Emitting Diode (LED) Console to speed curing of its patented, light-cured implants.

IlluminOss is the first and only company to develop balloon-like implants for supporting and repairing fragile and geriatric bone. The implants are inserted through a minimally invasive procedure into the patient's bone canal and are then infused with light-curing liquid.

Next, a fiber optic cable transfers a specific wavelength of blue light from the Light Console to cure the implant. The new Console reduces the implant hardening time, in some cases by up to 50%, which may decrease operative time and save hospital costs. By providing structural strength to fractured or weakened bone, IlluminOss implants provide patients with an opportunity for early mobility and return to daily living activities while also delivering a strong attachment for surgical plates and screws if necessary.

Although the original IlluminOss Light Console performs well, the company has embraced modern technologies with this new design to improve efficiency while reducing Console size by approximately 40%. The most important advancement is incorporating LEDs as the light source instead of a metal halide bulb. LEDs last much longer than bulbs and speed the curing time of the liquid inside the balloons.

Can intracanopy/intercanopy LED grow lights be used to increase greenhouse vegetable crop yields?

Hort Americas is partnering with a U.S. greenhouse vegetable grower to determine if intracanopy/intercanopy LED lighting can improve tomato yields with the potential to increase revenue.

A critical factor in growing greenhouse vegetables is ensuring the crops are produced in an environment that not only maximizes yields, but consistently produces predictable yields. A U.S. greenhouse tomato grower in the Midwest had installed high pressure sodium (HPS) lamps to maintain the proper top light levels year round to maintain consistent fruit production. The HPS lamps were used to provide supplemental light from November to March.

The tomato greenhouses are equipped with environmental sensors that measure light levels outside the greenhouses, at the top of the plant canopy and in the lower one-third of the canopy. Sensors also collect data on the substrate moisture level, relative humidity, carbon dioxide level, temperatures inside and outside the greenhouses and airflow rates. A Priva environmental control system collects the data enabling the grower to evaluate the data in order to manipulate the crops and environment to maximize fruit yields.

In addition to manipulating the environment, different plant dimensions are measured, including stem diameter and length, leaf length, number of tomato fruit clusters, and the speed at which plants flower. Using the data collected by these sensors, the grower can measure changes to the plants and establish a basis for steering the tomato crop. Collecting this data and analyzing it is particularly important when growers are looking to implement new technology that can improve plant growth and/or crop yields.

Because of the plant canopy, the amount of top light that reaches the interior of the plants, particularly vining crops, can be inconsistent and uneven. Intracanopy/intercanopy lighting, which uses LED grow lights to provide supplemental light within the crop canopy, has been shown to be successful in increasing yields with both ornamental (fresh cut roses) and vining vegetable crops (peppers and cucumbers).

Installing Arize LED grow lights to provide supplemental intracanopy light allowed for tomato plants to be spaced at a higher density of 3.5 plants per square meter compared to three plants per square meter for the control plants.

Installing grow lights within the plant canopy of greenhouse ornamental and vegetable crops has been referred to as intracanopy lighting, intercanopy lighting and interlighting. The terms have been used interchangeably by researchers and grow light fixture manufacturers and distributors. Regardless of the term used, the concept is the same—to provide supplemental light to the lower portions of the plants to increase photosynthesis with the potential to increase flower and fruit yields.

XLamp XP-G4 Incorporates Latest High-Power LED Advancements

According to analysts at Fortune Business Insights, the global LED lighting market is currently experiencing double digit year-on-year growth – with a 19.2% compound annual growth rate (CAGR) projected to continue between now and the end of the decade. This equates to it having an annual worth close to $300 billion by the end of that period. To get a share of the lucrative opportunity that this represents, LED manufacturers need to develop products that are capable of pushing the performance envelope and offering clear differentiation to end users.

By boosting performance characteristics, new LED generations have been able to bring about a marked reduction in the number of devices needing to be installed into lighting fixtures. As a consequence, there has been a lowering of overall fixture costs, while simultaneously making them more compact too. Innovations have resulted in elevated maximum drive current figures and lower thermal resistance values, as well as presenting a wider selection of corelated colour temperature (CCT) and colour rendering index (CRI) options. Furthermore, use of optics that are specifically suited to particular application scenarios has brought considerable rewards with it.

In any industry sector, when a well-established product line has dramatic improvements applied to it, current users as well as newcomers are going to take notice. High-power LEDs are no exception in this respect – with the upgrading of existing designs and brand new system implementations both benefitting as a result.

Initially introduced in 2009, the original Cree LED XLamp XP-G LEDs represented a breakthrough in performance and helped to kickstart a new era in solid-state illumination. Producing up to 400lumens of light output at 1A current levels and over 130Iumens/W at only 350mA, these emitter devices were up to 43% brighter and 53% more efficient than their predecessors.

The XLamp XP-G2 LEDs that followed a couple of years later increased the lumen output that could be supported up to 20%. When the XLamp XP-G3 devices arrived in 2016, a further 31% lumen output increase was realised, along with an 8% higher lumen/W figure. Now, with the announcement of the XLamp XP-G4 emitter products, the bar has been raised even further.

The devices in this new LED family can deliver 75% more lumens than their XP-G2 counterparts and have an even lower thermal resistance of 1.3°C/W. Wide acceptance of these LEDs is being seen in outdoor lighting, portable lighting, indoor lighting and solar-powered lighting implementations. In addition to the benefits of their performance augmentation, sharing the same footprint as the original XP-G, XP-G2 and XP-G3, XP-G4 LEDs means that users are provided with a seamless upgrade path and shortened design cycles.

The advances encompassed within the XLamp XP-G4 LED products are based on utilisation of the latest raw material, packaging and chip technologies. Effective use of ceramic high-power LEDs in many directional lighting applications often means employing a one-to-one configuration with specialised optics provided. With a smaller light emitting surface (LES) and up to 69% higher intensity than previous generations, XP-G4 LEDs create tighter beam angles and higher candela values than were previously possible.

With the XP-G3 family (see Figure 1), there had to be a traded-off with luminescence to maximise efficacy and long-term operational reliability. In contrast, the XPG4 family introduces a highly optimised optical profile that has been designed to accentuate on axis light output and provide substantial enhancements over the previous LED family. This allows XPG4 devices to deliver a 41% increase in maximum light output compared to XP-G3 devices, reaching up to 1,130lumens.

Use of proprietary technology leads to better directing of the emitted light into a narrower, more uniform cone. This results in a view angle full width half maximum (FWHM) of 120° in neutral white. The narrowed emission, reduced spill light and well-defined LES makes the new LED family highly suitable for directional lighting deployments – such as spotlights, premium torch and sports stadium lighting.

A flat and smooth phosphor layer results in a superior colour-over-angle profile. In addition, a 70° cut-off dramatically improves coupling efficiency with secondary optics compared to competing high-power LEDs.

The new XP-G generation is available in CCTs ranging from 1800K to 6500K and CRI options of 70, 80 and 90. In addition to the applications already mentioned, other uses include architectural, entertainment and horticultural lighting.
